# AutomationDirect GS11N-20P2

Hardware · `GS11N-20P2` · verification: source checked

The GS11N-20P2 is an enclosed micro AC variable frequency drive from the DURApulse GS10 series. It takes single-phase 230 VAC input and gives three-phase 230 VAC output for a 1/4 hp motor, using either sensorless vector control (SVC) or V/Hz control mode. It provides an RS-485 port running Modbus RTU or Modbus ASCII slave, analog and discrete I/O, and integrated dynamic braking.
